以高生型大丽花品种＂大金红＂为试材,在株高为20 cm时,采用叶片喷施和灌根2种施药方式施药1次,矮壮素施用浓度均为0（CK）、1 000 mg/L、1 500 mg/L、2 000 mg/L、2 500 mg/L和3 000 mg/L,通过测定植株形态指标（株高、节间长度、节数、叶面积、开花期、花期持续时间、花朵直径、花瓣数）和生理生化指标（叶片叶绿素和可溶性糖含量）,研究矮壮素施用方式和施用浓度对大丽花生长发育的影响。结果表明：矮壮素施用浓度为1 000～3 000 mg/L时,无论喷施还是灌根,均能够显著降低株高,增大叶片面积,延长花期,提高产量,且叶片叶绿素和可溶性糖含量增多;相同施药水平条件下,灌根效果优于喷施。用3 000 mg/L的矮壮素灌根效果最好,株高降低27.73%,叶面积增加43.91%,始花期推迟22 d,花期延长20 d,花径增大4.62 cm,花瓣数增多140片,叶片叶绿素和可溶性糖含量显著提高,大丽花的株型、观赏价值和开花品质都得到了明显改善。
以高生型大麗花品種＂大金紅＂為試材,在株高為20 cm時,採用葉片噴施和灌根2種施藥方式施藥1次,矮壯素施用濃度均為0（CK）、1 000 mg/L、1 500 mg/L、2 000 mg/L、2 500 mg/L和3 000 mg/L,通過測定植株形態指標（株高、節間長度、節數、葉麵積、開花期、花期持續時間、花朵直徑、花瓣數）和生理生化指標（葉片葉綠素和可溶性糖含量）,研究矮壯素施用方式和施用濃度對大麗花生長髮育的影響。結果錶明：矮壯素施用濃度為1 000～3 000 mg/L時,無論噴施還是灌根,均能夠顯著降低株高,增大葉片麵積,延長花期,提高產量,且葉片葉綠素和可溶性糖含量增多;相同施藥水平條件下,灌根效果優于噴施。用3 000 mg/L的矮壯素灌根效果最好,株高降低27.73%,葉麵積增加43.91%,始花期推遲22 d,花期延長20 d,花徑增大4.62 cm,花瓣數增多140片,葉片葉綠素和可溶性糖含量顯著提高,大麗花的株型、觀賞價值和開花品質都得到瞭明顯改善。

When the plant height of dahlia Dajinhong was 20 cm,chlorocholine chloride（CCC） with the concentrations of 0（CK）,1 000 mg/L,1 500 mg/L,2 000 mg/L,2 500 mg/L and 3 000 mg/L were sprayed on the leaves and poured to root one time respectively to test the morphological indices（plant height,internode length,nodes,leaf area,flowering stage,duration of flowering and stage,flower diameter and petal number） and the physiological indices（the contents of chlorophyll and soluble sugar）.The results showed that CCC with the concentration of 1 000-3 000 mg/L could decrease the plant height,increase the leaf area,prolong the flowering stage,increase the yield,improve the content of chlorophyll and soluble sugar.The efficience of soil irrigation was better than leaf spraying.The effect of soil irrigation with 3 000 mg/L CCC was the best,the plant height decreased by 27.73%,the leaf area increased by 43.91%,the first flowering dates delayed 22 d,the flowering stage prolonged 20 d,the flower diameter increased 4.62 cm,the petal number added 140 pieces,the contents of chlorophyll and soluble sugar significantly increased.The plant type,ornamental value and bloom quality were improved.
